Answer 1

Maybe you should try to use the mybatis starter dependency instead:

<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
</dependency>

Answer 2

I suffered the same problem after upgrading to spring boot 3.2. Upgrade dependencies to the latest version will do.

    <properties>
        <org.mybatis.version>3.5.14</org.mybatis.version>
        <org.mybatis.starter.version>3.0.3</org.mybatis.starter.version>
    </properties>

    <dependencies>

        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>${org.mybatis.version}</version>
        </dependency>

        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>${org.mybatis.starter.version}</version>
        </dependency>
    </dependencies>
